Description

Technical Field

[0001] This utility model relates to the field of pipe feeding technology, specifically a pipe feeding device for a pipe cutting machine. Background Technology

[0002] When using a pipe cutting machine, the pipes to be cut need to be transported. In order to reduce the labor intensity of the workers, a pipe feeding device is needed to transport the pipes.

[0003] Chinese Patent Publication No. CN222221931U discloses a pipe feeding device for a pipe cutting machine. This device clamps and feeds pipes by adjusting the position between the guide wheel and the positioning wheel. Although this feeding method can feed pipes, it can only feed a single pipe at a time. Once a single pipe has been fed, feeding must be stopped, the guide wheel and the positioning wheel must be moved apart, and the operator must manually place the next pipe between the guide wheel and the positioning wheel and clamp it again before feeding can continue. This process involves a long downtime and is quite cumbersome, affecting the subsequent processing of the pipes. Therefore, a pipe feeding device for a pipe cutting machine is proposed to address the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: A pipe cutting machine pipe feeding device of this utility model includes a frame, a pulley rotatably connected to the inner side of the frame, a belt rotatably connected to the outer side of the pulley, a motor fixedly connected to the outer side of the frame, one side of the pulley and the output end of the motor fixedly connected, a groove formed on the inner side of the belt, a clamping plate fixedly connected to the inner side of the frame, the clamping plate and the groove slidably connected, a rubber pad fixedly connected to the side of the belt that is close to each other, a placement groove formed on the inner side of the frame, an electric roller provided on the inner side of the frame, and a first hydraulic cylinder fixedly connected to the outer side of the frame, with a pressure plate fixedly connected to the output end of the first hydraulic cylinder; this step involves setting up a belt, clamping plate, rubber pad, and pressure plate... The device uses a plate to place multiple pipes inside a placement groove. The upper pipes press down on the lower pipes, with the bottom pipe pressing against a rubber pad, causing the pad to deform. At this point, a clamping plate limits the groove and the belt, preventing the belt from being pulled away from the pulley by the rubber pad. The rotation of the pulley causes the belt to rotate, and the friction between the rubber pad and the pipe moves the pipe out of the device for cutting. When the pipe moves completely away from the rubber pad, one end moves to the top of the electric roller. The pressure plate presses down, allowing the pipe to adhere to the electric roller and continue moving. Then, subsequent pipes continue to be pressed against each other and conveyed by the rubber pad, allowing the pipes to be continuously conveyed, thus improving the practicality of the device.

[0006] Preferably, a screw with both positive and negative threads is rotatably connected to the inner side of the frame, and a clamping block is threadedly connected to the outer side of the screw with both positive and negative threads. The clamping block and the frame are slidably connected. This step, by setting the screw with both positive and negative threads and the clamping block, allows the clamping blocks to move closer together when dealing with smaller pipes. This causes the clamping blocks to enter the inner side of the placement groove, thereby further reducing the size of the placement groove. This makes it easier for the placement groove to limit the pipe, making the pipe transportation more stable and improving the stability of the device.

[0007] Preferably, a second hydraulic cylinder is fixedly connected to the outer side of the frame, and a lifting plate is fixedly connected to the upper side of the second hydraulic cylinder. This step, by setting the second hydraulic cylinder and the lifting plate, allows the lifting plate to be raised when the pipe is pressed down to fit tightly against the rubber pad. This allows the lifting plate to further compress the rubber pad, further increasing the friction between the rubber pad and the pipe. This makes the conveying of the pipe by the rubber pad through friction more stable, improving the stability of the device.

[0008] Preferably, a fixing groove is provided on the inner side of the lifting plate, and a roller is rotatably connected to the inner side of the fixing groove. The roller and the rubber pad are used in conjunction. This step, by setting the fixing groove and the roller, ensures that when the lifting plate is raised to be close to the rubber pad, the roller contacts the rubber pad before the lifting plate, so that the rubber pad does not contact the lifting plate. When the rubber pad rotates, the friction between the rubber pad and the roller will cause the roller to rotate, thereby reducing the friction between the roller and the rubber pad, reducing the resistance on the rubber pad, and improving the stability of the device.

[0009] Preferably, the surface of the positive and negative threaded screws has a slot, and a plug is slidably connected to the inside of the slot. This step, by setting the slot and the plug, allows the plug to be inserted into the slot inside the two positive and negative threaded screws after the positive and negative threaded screws have rotated, thereby fixing the two positive and negative threaded screws synchronously, making the position of the clamp more stable and improving the stability of the device.

[0010] Preferably, a mounting plate is fixedly connected to the outside of the frame, and the surface of the mounting plate is provided with a mounting groove. This step, by setting up the mounting plate and the mounting groove, makes it easier to install and fix the device when it is placed near the feed inlet of the pipe cutter by screwing the bolts into the mounting groove and the mounting location, thereby improving the convenience of device installation.

[0011] The advantages of this utility model are:

[0012] 1. This utility model uses a belt, clamping plate, rubber pad, and pressure plate to place multiple pipes inside a placement groove. The upper pipes press down on the lower pipes, with the lowest pipe pressing against the rubber pad, causing the rubber pad to deform. At this time, the clamping plate limits the groove and the belt, preventing the belt from being pulled away from the pulley by the rubber pad. The rotation of the pulley causes the belt to drive the rubber pad to rotate. Through the friction between the rubber pad and the pipe, the pipe moves out of the device for cutting. When the pipe moves to the point of being completely separated from the rubber pad, one end moves to the upper side of the electric roller. The pressure plate presses down, allowing the pipe to stick to the electric roller and continue moving. Then, subsequent pipes continue to be squeezed against each other and conveyed by the rubber pad, allowing the pipes to be continuously conveyed, thus improving the practicality of the device.

[0013] 2. By setting up positive and negative threaded screws and clamping blocks, this utility model allows the clamping blocks to move closer together when dealing with smaller pipes. This causes the clamping blocks to enter the inner side of the placement groove, thereby further reducing the size of the placement groove. This makes it easier for the placement groove to limit the pipe, making the pipe transportation more stable and improving the stability of the device. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] Specific implementation examples are given below.

[0023] Please see Figures 1 to 5 As shown, a pipe-feeding device for a pipe cutting machine includes a frame 1. A pulley 2 is rotatably connected to the inner side of the frame 1, and a belt 3 is rotatably connected to the outer side of the pulley 2. A motor 4 is fixedly connected to the outer side of the frame 1. One side of the pulley 2 and the output end of the motor 4 are fixedly connected. A groove 5 is formed on the inner side of the belt 3. A clamping plate 6 is fixedly connected to the inner side of the frame 1, and the clamping plate 6 and the groove 5 are slidably connected. A rubber pad 7 is fixedly connected to one side of the belt 3 that is close to the other. A placement groove 8 is formed on the inner side of the frame 1. An electric roller 9 is arranged on the inner side of the frame 1. A first hydraulic cylinder 10 is fixedly connected to the outer side of the frame 1, and a pressure plate 11 is fixedly connected to the output end of the first hydraulic cylinder 10. This step, by setting up the belt 3, clamping plate 6, rubber pad 7, and pressure plate 11, feeds multiple pipes... The material is placed inside the placement groove 8. The upper pipe presses down on the lower pipe, and the lowest pipe presses down and presses tightly against the rubber pad 7, causing the rubber pad 7 to deform. At this time, the clamping plate 6 limits the groove 5 and the belt 3, so that the belt 3 will not be pulled by the rubber pad 7 to separate from the pulley 2. The rotation of the pulley 2 causes the belt 3 to drive the rubber pad 7 to rotate. Through the friction between the rubber pad 7 and the pipe, the pipe is moved out of the device for cutting. When the pipe moves to the point of being completely separated from the rubber pad 7, one end will move to the upper side of the electric roller 9. Through the pressure of the pressure plate 11, the pipe can be pressed tightly against the electric roller 9 and continue to move. Then, the subsequent pipes continue to squeeze against each other and are conveyed by the rubber pad 7, so that the pipe can be continuously conveyed, improving the practicality of the device.

[0024] Furthermore, such as Figure 1 and Figure 4As shown, a screw rod 12 with both positive and negative threads is rotatably connected to the inner side of the frame 1, and a clamping block 13 is threadedly connected to the outer side of the screw rod 12. The clamping block 13 and the frame 1 are slidably connected. This step, by setting the screw rod 12 with both positive and negative threads and the clamping block 13, allows the clamping block 13 to move closer together when dealing with smaller pipes by rotating the screw rod 12. This causes the clamping block 13 to enter the inner side of the placement groove 8, thereby further reducing the size of the placement groove 8. This makes it easier for the placement groove 8 to limit the pipe, making the pipe transportation more stable and improving the stability of the device.

[0025] Furthermore, such as Figure 1 and Figure 5 As shown, a second hydraulic cylinder 14 is fixedly connected to the outside of the frame 1, and a lifting plate 15 is fixedly connected to the upper side of the second hydraulic cylinder 14. This step, by setting the second hydraulic cylinder 14 and the lifting plate 15, allows the lifting plate 15 to be lifted by the second hydraulic cylinder 14 when the pipe is pressed down to fit the rubber pad 7. This allows the lifting plate 15 to further compress the rubber pad 7, further increasing the friction between the rubber pad 7 and the pipe. This makes the conveying of the pipe by the rubber pad 7 through friction more stable, improving the stability of the device.

[0026] Furthermore, such as Figure 5 As shown, a fixing groove 16 is provided on the inner side of the lifting plate 15, and a roller 17 is rotatably connected to the inner side of the fixing groove 16. The roller 17 and the rubber pad 7 are used in conjunction. By setting the fixing groove 16 and the roller 17, when the lifting plate 15 is raised to be close to the rubber pad 7, the roller 17 contacts the rubber pad 7 before the lifting plate 15, so that the rubber pad 7 does not contact the lifting plate 15. When the rubber pad 7 rotates, the friction between the rubber pad 7 and the roller 17 will cause the roller 17 to rotate, thereby reducing the friction between the roller 17 and the rubber pad 7, reducing the resistance on the rubber pad 7, and improving the stability of the device.

[0027] Furthermore, such as Figure 2 and Figure 4 As shown, the surface of the threaded screw 12 has a slot 18, and a rod 19 is slidably connected to the inside of the slot 18. This step, by setting the slot 18 and the rod 19, allows the rod 19 to be inserted into the slot 18 inside the two threaded screws 12 after they have rotated, thereby synchronously fixing the two threaded screws 12, making the position of the clamping block 13 more stable, and improving the stability of the device.

[0028] Furthermore, such as Figure 1As shown, a mounting plate 20 is fixedly connected to the outside of the frame 1, and a mounting groove 21 is provided on the surface of the mounting plate 20. This step, by setting the mounting plate 20 and the mounting groove 21, makes it easier to install and fix the device when it is set near the feed port of the pipe cutter by screwing the bolts into the mounting groove 21 and the installation location, thereby improving the convenience of device installation.

[0029] Working principle: First, rotate the forward and reverse threaded screws 12 to bring the clamping blocks 13 closer together and into the inner side of the placement groove 8, thereby adjusting the placement groove 8 to a suitable width. Multiple pipes are then placed inside the placement groove 8, with the upper pipes pressing down on the lower pipes. The lowest pipe is pressed tightly against the rubber pad 7, causing the rubber pad 7 to deform. The second hydraulic cylinder 14 drives the lifting plate 15 to rise, which in turn drives the roller 17 to rise, further compressing the rubber pad 7 and increasing the friction between the rubber pad 7 and the pipes. At this point, the clamping plate 6 limits the groove 5 and the belt 3, preventing the belt 3 from being pulled away from the pulley 2 by the rubber pad 7. The motor 4 then drives the pulley 2 to rotate. The rotation of pulley 2 causes belt 3 to drive rubber pad 7 to rotate. The friction between rubber pad 7 and pipe causes pipe to move out of the cutting device. When one end of pipe moves to the upper side of electric roller 9, the first hydraulic cylinder 10 drives pressure plate 11 to press down. The pressure plate 11 presses down, allowing pipe to stick to electric roller 9. Even after the bottom pipe moves to completely separate from rubber pad 7, electric roller 9 can still drive pipe to continue moving, allowing the bottom pipe to move to completely separate from the pipe above it. Then, subsequent pipes continue to squeeze each other, causing the bottom pipe to move to contact rubber pad 7 again. The rotation of rubber pad 7 allows for continued conveying.
